As your instructor, I recognize that students face a variety of challenges, and that these challenges are not evenly distributed across individuals for a variety of reasons, including:
My goal is to be as flexible as I can be with each student so that everyone can meet the learning objectives for the course despite the difficulties we face.
Lets take a minute to introduce ourselves.
Data science is an industry buzzword and cliche
From wikipedia:
“Data science is an interdisciplinary field about processes and systems to extract knowledge or insights from data.
| Assignment | Percent |
|---|---|
| Weekly homework assignments - submitted on Blackboard | 40% |
| Practical Exam 1 | 12.5% |
| Practical Exam 2 | 12.5% |
| Original Analysis (due Dec 5th) | 15% |
| Critical Evaluation (due Nov 7th) | 10% |
| Attendance/Participation in class | 10% |
Classes will be held in person, and attendance will be taken.
Classes will not be recorded.
Your primary study materials will be the lecture slides (available on course website).
There are weekly homework assignments in this class.
These are where you will really learn to do data analysis. I will walk you through the concepts in class, but you will learn by doing.
Homework assignments will be uploaded to Blackboard, and are due by the beginning of class on their due date.
Note: First homework assignment is due next week.
I am not a monster, but in order for you to learn, you need to do these in a timely fashion, because concepts build on one another fast!
You are free to use available tools to help complete homework. You are expected, based on the GW honor code to cite sources if you copy and paste code. This includes output from ChatGPT.
ChatGPT is an incredibly useful course for producing code, but it can’t teach you how to write code, or to understand it. If you don’t understand what you are doing on homework, you will not be able to pass the exams, which will be completed without ChatGPT.
When you leave this course, I hope you are empowered to:
R is an open-source language and environment for statistical computing and graphics.
open-source means that anyone can look at the code to see how it works.

One of the top 10 most widely used programming languages in the world in 2018.

A rapidly growing system of user contributed packages.
Let’s check out the website then we will do the introduction to R
We are going to do an interactive tutorial that I wrote.
Download the folder at this link: link
Be sure you have installed the learnr package. Who needs help doing this?
We will spend about 40 minutes on the tutorial
